StoneCare4U Essential Matt Finish Sandstone Sealer 25L

Protect your natural sandstone, limestone, and slate surfaces with StoneCare4U's Essential Matt Finish Sandstone Sealer. This fast-drying, 25L sealer delivers a durable matte finish that powerfully resists stains and provides exceptional water resistance for long-lasting protection. Its unique formula prevents efflorescence and inhibits algae growth, creating a self-cleaning surface that minimizes maintenance. The sealer significantly reduces water absorption without blocking pores, allowing the material to breathe and release moisture. It offers outstanding water repellence and stain resistance. For optimal results, ensure the surface is completely clean and dry for at least 72 hours in clear, dry weather before application (13-23°C). Apply two "wet-on-wet" coats using a low-pressure sprayer, roller, natural fibre brush, or sponge. Don't dilute. The surface will be dry in 45-60 minutes. Stop application immediately if rain is forecast or begins, protecting freshly treated areas until completely dry for at least 6 hours. Always test in an inconspicuous area first, as the sealer may alter colour. Protect unsealed surfaces with masking material. Wear appropriate safety gear (gloves, eyewear, mask, clothing) during application. Maintain sealed areas with a mild, pH-neutral cleaner or a low-concentration outdoor cleaner, avoid harsh or abrasive agents. Coverage: 4-6 sq m per litre (porosity may affect coverage.
